FERIEENTATION BUNG.

Application filed January 25, 1923. Serial No. 614,937,

To all whom it may concern:

Be it known that I, JOSEPH B. FISCHER,

a citizen of the United States of America,

residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Fermentation Brings, of which the following is a specification.

This invention relates to that class of sealing bungs for barrels, having provisions for the escape of gases arising from the fermentation of the contents of the barrel and which at the same time prevents any ingress of atmospheric air into the interior of the barrel. And the present improvement has for its various objects To provide a simple and efficient formation and combination of parts whereby an effective sealing action is attained, and in which the parts are combined and connected for ready disconnection for cleaning and 7 like operations.

To provide a structural formation of the bung body adapting the same to fit widely 2 different sizes of barrel bung holes met with in the trade, and which affords a compact formation of said body by which too great a projection of the same into the interior of the barrel is avoided, all as will hereinafter 1" more fully appear.

In the accompanying drawing Fig. 1, is a side elevation of a sealing bung for barrels, embodying the present improvement.

Referring to the drawing:1, designates the bung body, which in the present improvement is formed by a pair of truncated cones 2 and 3, connected base to base, with the diameters of said cones of different diameters, and preferably with the truncated end of one cone 2 having a diameter equal to the base of the companion cone 3. With such construction the bung body, by a reversal end for end, i adapted to fit any ordinary diameter of bung opening in different barrels with which the device is used, without any undue and objectionable projection of the bung body into the interior of the barrel.

The bung body 1 is provided with a central orifice extending the entire depth of the body and adapted to receive the tubular member of the sealing means now to be described.

a, designates a tube of a goose neck or re turn bend shape, one depending leg 5 of which is adapted to fit in the above described orifice of the bung body 1 and be packed therein in an air tight manner by an elastic bushing 6. The other depending leg 7 of the tube 4 aforesaid, is in spaced parallel relation to the aforesaid leg 5 and has connections as follows 8, designates a transparent vessel or bottle, open at top for the insertion of the lower portion of the aforesaid depending leg 7. The vessel 8 is provided with a neck preferably screw threaded for detachable connection with a similarly formed closure cap 9 fixedly attached to said depending leg 7, at its mid-height. The vessel or bottle 8 is adapted to contain a fluid filling into which the lower end of the depending leg 7 dips and is sealed against any back flow of air into the interior of a fermenting barrel to which the device is applied.

Proper venting of the vessel or bottle 8 is attained by an outlet orifice 10 formed in the cap 9 aforesaid.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a sealing bung for fermentation barrels, a hung body having a central orifice, a tube of a return bend shape having one leg fitted in said orifice, a closure cap secured to the other leg of said tube at the mid-height of the leg and provided with a vent orifice and a downturued skirt portion, and an open top vessel having detachable engagement with said skirt portion and adapted to enclose the depending part of tube leg associated with the closure cap and maintain a sealing fluid around said leg end.

2. In a sealing bung of the type described, a bung body formed by a pair of truncated cone portions connected base to base. with the truncated end of one cone portion having a diameter approximately the diameter of the base of the other cone portion.
